EClinicalMedicine 2024; 70:102532. [PMID: 38685925 PMCID: PMC11056414 DOI: 10.1016/j.eclinm.2024.102532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 02/21/2024] [Accepted: 02/22/2024] [Indexed: 05/02/2024] Open
Abstract
Background The World Health Organization (WHO) recommends tenofovir disoproxil fumarate (TDF)-based oral pre-exposure prophylaxis (PrEP), the dapivirine vaginal ring, and long-acting intramuscular injectable cabotegravir (CAB-LA) for HIV prevention in populations at substantial risk of HIV infection. Pregnancy is a period of elevated risk of maternal HIV infection and transmission to the infant. This systematic review and meta-analysis assessed the risk of adverse perinatal outcomes among HIV-negative pregnant women with exposure to any PrEP modality. Methods We conducted a systematic review by searching Medline, EMBASE, CINAHL, Global Health, the Cochrane Library, WHO ICTR, ISRCTN, PACTR, and ClinicalTrials.gov for studies published between 1 January 2000 and 29 August 2023. We included studies reporting on the association of antenatal exposure to any PrEP modality with 13 perinatal outcomes: preterm birth (PTB), very PTB, spontaneous PTB, spontaneous very PTB, low birthweight (LBW), very LBW, term LBW, preterm LBW, small for gestational age (SGA), very SGA, miscarriage, stillbirth, or neonatal death (NND). Quality assessments of included studies were performed. Fixed-effect meta-analyses were conducted to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs). The protocol is registered with PROSPERO, CRD42022339825. Findings Of 18,598 citations identified, 13 studies (eight randomised controlled trials (RCTs) and five cohort studies), assessing 8712 pregnant women in Africa, were included. Oral PrEP, compared to no PrEP, was not associated with PTB in meta-analyses of six RCTs (OR 0.73, 95% CI 0.43-1.26; I2 = 0.0%) or five unadjusted cohort studies (OR 0.84, 95% CI 0.69-1.03; I2 = 0.0%), but was associated with a reduced risk of PTB in three adjusted cohort studies (aOR 0.67; 95% CI 0.52-0.88, I2 = 0.0%). There was no association of oral PrEP with LBW, vLBW, SGA, or NND, compared to no PrEP. There was no association with PTB when oral TDF/emtricitabine (FTC) PrEP, oral TDF PrEP, and tenofovir vaginal gel were compared to each other. There was no association of the dapivirine vaginal ring with PTB or NND, compared to placebo or oral TDF/FTC PrEP. We found no data on CAB-LA. Interpretation We found no evidence of adverse perinatal outcomes associated with PrEP exposure during pregnancy. Our findings support the WHO recommendation to provide oral PrEP to women of reproductive age and pregnant women. More data is needed to assess the safety of all PrEP modalities in pregnancy. Funding None.

Abstract
INTRODUCTION The HIV/AIDS epidemic has been one of the greatest challenges in global health, significantly affecting women of reproductive potential. Considerable advances in antiretroviral therapy for women living with HIV have contributed to improvements in quality of life, better reproductive and birth outcomes, and a reduced risk of perinatal transmission. AREAS COVERED Despite the progress made, persistent challenges in access and adherence to antiretroviral drugs may limit their benefits for some women. More pharmacokinetic and safety studies in pregnant and lactating women are urgently needed, as are prospective surveillance systems to evaluate associations between fetal and infant antiretroviral exposures, drug-drug interactions, and pregnancy outcomes. EXPERT OPINION Multipurpose technologies, such as combined HIV and other STI or unintended pregnancy prevention, and innovative delivery methods, such as the development of long-acting antiretrovirals, have the potential to reduce adherence challenges and enhance quality of life for women with HIV. Parallel advances in drug safety testing and surveillance are needed to ensure the health and safety of women with or at risk for HIV and children at risk for perinatal transmission.

Abstract
Black cisgender women (hereafter referred to as "women") have disproportionately high rates of HIV infection yet low rates of pre-exposure prophylaxis (PrEP) utilization. Barriers to PrEP uptake exist at the system, provider, and individual/client level. To learn how existing training and advertising can be adapted to address race- and sex-based gaps within PrEP service delivery, we conducted focus groups with providers and Black women. Participants were recruited at three health care organizations in the Midwest and South, screened for eligibility, and consented verbally. Focus groups occurred from August 2022 to February 2023. Women were asked about their knowledge and thoughts on PrEP. Providers were asked about factors influencing their decision-making about PrEP. A codebook was developed based on the Consolidated Framework for Implementation Research. Transcripts were coded using the Stanford Lightning Report Method. We completed four focus groups with 10 providers and 9 focus groups with 25 women. Three major themes emerged: (1) low comfort level and limited cultural sensitivity/competency among providers discussing HIV risk and PrEP with Black women, (2) women's concerns about PrEP's side effects and safety during pregnancy, and (3) lack of Black women representation in PrEP advertisement/educational materials. In addition, women in the South reported general medical mistrust and specific misconceptions about PrEP. PrEP trainings for providers need detailed information about the safety of PrEP for women and should include role-playing to enhance cultural competency. Likewise, PrEP advertisements/materials should incorporate information regarding side effects and images/experiences of Black women to increase PrEP awareness and uptake among this population. Clinical Trial Registration Number: NCT05626452.

FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1221101.

Abstract
The risk of HIV acquisition is higher during pregnancy and postpartum than other times. Newly acquired maternal HIV infection associated with high primary viraemia, substantially increases the risk of vertical HIV transmission. Pre-exposure prophylaxis (PrEP) reduces the risk of HIV acquisition. Currently available products include oral tenofovir/emtricitabine (TDF/FTC) and tenofovir alafenamide (TAF)/FTC), long-acting cabotegravir (CAB-LA) and the dapivirine ring (DVR). All except oral TDF/FTC have limited safety data available for use in pregnant and breastfeeding women. The safety of new PrEP agents for pregnant women and the fetus, infant and child, either exposed in utero or during breastfeeding is an ongoing concern for health care workers and pregnant and breastfeeding women, particularly as the safety risk appetite for antiretroviral (ARV) agents used as PrEP is lower in pregnant and breastfeeding women who are HIV-uninfected, compared to women living with HIV taking ARVs as treatment. With the widespread rollout of TDF/FTC among pregnant women in South Africa and other low-middle income countries (LMIC) and the potential introduction of new PrEP agents for pregnant women, there is a need for safety surveillance systems to identify potential signals of risk to either the mother or fetus, measure the burden of such a risk, and where appropriate, provide specific reassurance to PrEP users. Safety data needs to be collected across the continuum of the product life cycle from pre-licensure into the post-marketing period, building a safety profile through both passive and active surveillance systems, recognising the strengths and limitations of each, and the potential for bias and confounding. Pharmacovigilance systems that aim to assess the risk of adverse birth outcomes in pregnant women exposed to PrEP and other agents need to consider the special requirements of pregnancy epidemiology to ensure that the data derived from surveillance are sufficiently robust to inform treatment policies. Here we review the known safety profiles of currently available PrEP candidates in women of child-bearing potential, pregnancy and breastfeeding and discuss pragmatic approaches for such surveillance in HIV-endemic LMICs.

Abstract
BACKGROUND We assessed bone and kidney outcomes in infants randomized postdelivery as mother-infant pairs within the IMPAACT PROMISE trial to maternal tenofovir disoproxil fumarate-based antiretroviral treatment (mART) or infant nevirapine prophylaxis (iNVP) to prevent breastfeeding HIV transmission. METHODS Infants were coenrolled in the P1084s substudy on randomization day and followed through Week 74. Lumbar spine bone mineral content (LS-BMC) was assessed at entry (6-21 age days) and Week 26 by dual-energy x-ray absorptiometry. Creatinine clearance (CrCl) was calculated at entry; Weeks 10, 26, and 74. Student t tests compared mean LS-BMC and CrCl at Week 26 and mean change from entry between arms. RESULTS Of 400 enrolled infants, the mean (SD; n) for entry LS-BMC was 1.68 g (0.35; n = 363) and CrCl was 64.2 mL/min/1.73 m 2 (24.6; n = 357). At Week 26, 98% of infants were breastfeeding and 96% on their assigned HIV prevention strategy. The mean (SD) Week 26 LS-BMC was 2.64 g (0.48) for mART and 2.77 g (0.44) for iNVP; mean difference (95% confidence interval [CI]) -0.13 g (-0.22 to -0.04), P = 0.007, n = 375/398 (94%). Mean absolute (-0.14 g [-0.23 to -0.06]) and percent (-10.88% [-18.53 to -3.23]) increase in LS-BMC from entry was smaller for mART than iNVP. At Week 26, the mean (SD) CrCl was 130.0 mL/min/1.73 m 2 (34.9) for mART vs. 126.1 mL/min/1.73 m 2 (30.0) for iNVP; mean difference (95% CI) 3.8 (-3.0 to 10.7), P = 0.27, n = 349/398 (88%). CONCLUSION Week 26 mean LS-BMC was lower in infants in the mART group compared with the iNVP group. However, this difference (∼0.23 g) was less than one-half SD, considered potentially clinically relevant. No infant renal safety concerns were observed.

Abstract
INTRODUCTION Maternal HIV infection is associated with increased risk of having a preterm delivery, low birth weight baby, small for gestational age baby and stillbirth. Maternal use of combination antiretroviral treatment is also associated with preterm delivery and low birth weight, although the effects vary by the type of drugs and timing of initiation. OBJECTIVE To examine time trends in adverse perinatal outcomes among HIV-positive compared with HIV-negative women. DESIGN Registry-based cohort study. SETTING Northern Tanzania, 2000-2018. STUDY SAMPLE Mother-baby pairs of singleton deliveries (n = 41 156). METHODS Perinatal outcomes of HIV-positive women were compared with HIV-negative women during time periods representing shifts in prevention of mother-to-child transmission guidelines. Monotherapy was used as first-line therapy before 2007 while combination antiretroviral treatment was routinely used from 2007. Log binomial and quantile regression were used to analyze the data. MAIN OUTCOME MEASURES Preterm delivery, low birth weight, perinatal death, stillbirth, low Apgar score, transfer to neonatal care unit and small for gestational age. RESULTS Overall, maternal HIV infection was associated with a higher risk of low birth weight and small for gestational age. Moreover, this pattern became more pronounced over time for low birth weight, the last time period being an exception. For other outcomes we found none or only a small overall association with maternal HIV infection, although a trend towards higher risk over time in HIV-positive compared with HIV-negative women was observed for preterm delivery and perinatal death. Quantile regression showed an increase in birth weight in babies born to HIV-negative women over time and a corresponding decline in birth weight in babies born to HIV-positive women. CONCLUSION Unfavourable trends in some of the selected perinatal outcomes were seen for HIV-positive compared with HIV-negative women. Potential side-effects of combination antiretroviral treatment in pregnancy should be further explored.

Lancet HIV 2023; 10:e154-e163.

Abstract
BACKGROUND The safety of tenofovir disoproxil fumarate and emtricitabine as pre-exposure prophylaxis (PrEP) in pregnant women not living with HIV is uncertain. We aimed to compare pregnancy and neonatal outcomes in women exposed and not exposed to PrEP during pregnancy. METHODS In this single-site, open-label, randomised, non-inferiority trial in Durban, South Africa, we evaluated pregnancy and neonatal outcomes in pregnant women aged 18 years or older, not living with HIV, and at 14-28 weeks' gestation at the time of enrolment. Eligible participants were randomly assigned (1:1) using a computer-generated permuted block (block size of ten) randomisation list to immediate initiation or deferred initiation of PrEP until breastfeeding cessation. Participants in the immediate PrEP group received a monthly supply of once daily oral tenofovir disoproxil fumarate 300 mg and emtricitabine 200 mg. Participants in the deferred PrEP group received standard of care for HIV prevention. The primary outcomes were the occurrence of preterm live birth (<37 weeks gestational age) and very preterm birth (<34 weeks gestational age) determined by menstrual dating, low birthweight (<2500 g), very low birthweight (<1500 g), stillbirth (≥20 weeks gestational age), and small for gestational age (birthweight less than the tenth percentile). Post-natal safety outcomes will be reported elsewhere. We used binomial regression models to estimate risk differences and two-sided 90% CIs. Immediate PrEP was non-inferior to deferred PrEP if the upper bound of the 90% CI of the risk difference was less than the upper predefined non-inferiority margin for preterm birth (7·5%), very preterm birth (2·6%), low birthweight (5·5%), very low birthweight (1·2%), stillbirth (1·0%), and small for gestational age (3·7%). All outcomes were analysed in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT3227731. FINDINGS Between Sept 25, 2017, and Dec 6, 2019, we screened 693 women, of whom 540 were randomly assigned to immediate PrEP (n=271) or deferred PrEP (n=269). The median gestational age was 19 weeks (IQR 15-23 for immediate PrEP and 16-23 for deferred PrEP). The risk difference between the immediate PrEP group and the deferred PrEP group for preterm birth was -4·7% (90% CI -10·7 to 1·2; immediate PrEP was non-inferior), for very preterm birth was 0·6% (-3·4 to 4·6; upper limit exceeded the non-inferiority margin), for low birthweight was 2·5% (-1·6 to 6·6; upper limit exceeded the non-inferiority margin), for very low birthweight was 0% (-1·4 to 1·4; upper limit exceeded the non-inferiority margin), for stillbirth was 1·2% (-1·5 to 3·8; upper limit exceeded the non-inferiority margin), and for small for gestational age was 0·9% (-1·2 to 2·9; immediate PrEP was non-inferior). INTERPRETATION In our study, PrEP was not associated with preterm birth or small for gestational age infants. Our data support the use of tenofovir disoproxil fumarate and emtricitabine in pregnancy and our reassuring findings can be used to allay safety concerns among pregnant women.

Abstract
The majority of pediatric human immunodeficiency virus (HIV) infections are the result of vertical transmissions that occur during pregnancy, childbirth, and breastfeeding. The treatment of all pregnant persons living with HIV remains a global health initiative. Early and consistent use of antiretroviral therapy throughout pregnancy and childbirth drastically reduces the risk of perinatal transmission of HIV, resulting in fewer children living with the disease worldwide. Given that the maternal HIV viral load is the strongest predictor of perinatal transmission, suppressive antiretroviral treatment during pregnancy is the principal means to eliminate transmission of HIV from mother to child. With the use of combined antiretroviral therapy, typically with dual-nucleoside reverse transcriptase inhibitors plus an integrase strand transfer inhibitor or a ritonavir-boosted protease inhibitor, HIV-infected mothers can now achieve virologic suppression to undetectable levels and yield a perinatal transmission rate of less than 2%. Important considerations of HIV treatment in pregnancy include the safety and efficacy of antiretroviral drugs, altered pregnancy-related pharmacokinetics, potential for birth defects or adverse neonatal outcomes, and individualized delivery planning based on maternal viral load.

Abstract
Whether telbivudine (LdT) treatment to pregnant women with hepatitis B surface antigen (HBsAg) affects infant immune response to hepatitis B vaccine (HepB) has not been investigated. A total of 127 HBsAg positive mothers and their neonates were enrolled and followed up at 11–13 months. Mothers took LdT (LdT group) or did not receive antiviral therapy (control group). Infant anti-HBs, immune cells and cytokines were measured after HepB was administered according to 0-1-6 procedure. We performed a 1:3 propensity score matching (PSM). Immune indexes in the two groups were compared. Baseline characteristics of mother-baby pairs were comparable in LdT group and control group. Infant anti-HBs geometric mean concentration (GMC) did not differ significantly between the two groups [767.70 (745.35) vs. 711.90 (819.60), P = .599]. There was no difference between the two groups in infant positive rate of anti-HBs [97.8% (91/93) vs. 97.1% (33/34), P = .999] and strong positive rate of anti-HBs [40.9% (38/93) vs. 44.1% (15/34), P = .742]. Infants with negative, low, medium, and high anti-HBs levels were similarly distributed between the two groups (P = .511). No differences in proportion of helper T cells, cytotoxic T cells, B cells, myeloid dendritic cells, and plasmacytoid dendritic cells of infants (P > .05) were detected between the two groups. Children in the LdT and control group had comparable levels of interleukin-2, interleukin-4, interleukin-6, interleukin-10, interleukin-12, interferon-α, interferon-γ and tumor necrosis factor-α (P > .05). Intrauterine exposure to LdT was safe to infant immune response to HepB after birth.

[PMID: 35312156 DOI: 10.1111/liv.15249] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 01/19/2022] [Accepted: 03/17/2022] [Indexed: 02/13/2023]
Abstract
Hepatitis B virus (HBV) is a global health problem. Vertical transmission of HBV from HBV surface antigen (HBsAg)-positive mothers to their infants is the most common cause of HBV infection worldwide. The use of passive-active immunoprophylaxis is >90% effective in reducing the risk of vertical transmission, but immunoprophylaxis failure can occur in infants born to mothers with high viraemia. Thus, it is recommended that pregnant women with HBV-DNA level >200 000 IU/ml receive nucleos(t)ide analogue (NA) treatment [i.e. tenofovir disoproxil fumarate (TDF), lamivudine or telbivudine] during third trimester to prevent infant immunoprophylaxis failure. TDF is recommended as the first-line therapy based on available data on efficacy, safety and resistance profile. However, maternal immunological reconstitution following parturition can increase immune-mediated flares to viral antigens that is potentially exacerbated following TDF withdrawal. In this article, we review available data on the efficacy and safety of TDF administration to prevent HBV mother-to-child transmission. We also discuss changes in maternal viral markers [i.e. HBV-DNA, HBV e antigen and HBsAg] and alanine aminotransferase during follow-up post-partum in mothers received NA to prevent HBV vertical transmission.

Plasma and breast milk pharmacokinetics of tenofovir alafenamide in mothers with chronic hepatitis B infection. Aliment Pharmacol Ther 2022; 56:510-518. [PMID: 35599363 DOI: 10.1111/apt.17040] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 05/06/2022] [Accepted: 05/08/2022] [Indexed: 01/26/2023]
Abstract
BACKGROUND Antenatal antiviral therapy (AVT) is effective in preventing mother-to-child transmission (MTCT) in chronic hepatitis B (CHB); tenofovir disoproxil fumarate (TDF) is the preferred agent. Tenofovir alafenamide (TAF) is a prodrug of tenofovir (TFV) similar to TDF, with improved bone and renal safety. There are no data on TAF breast milk pharmacokinetics and exposure to breastfeeding infants in CHB. AIM To assess the pharmacokinetics of TAF/TFV in breastfeeding women with CHB on TAF monotherapy. METHODS Pregnant women with CHB requiring AVT commenced TAF 25 mg daily at third trimester or postpartum. Sample collection occurred while breastfeeding and taking TAF for minimum 4 weeks. Maternal blood, breast milk and infant urine samples were collected. Drug concentrations were measured by LCMS/MS analyses using validated methods. Non-compartmental analyses were performed to quantify the pharmacokinetic parameters. RESULTS Eight women provided samples. In breast milk and plasma, median TAF half-life was 0.81 and 0.94 h, respectively, and Cmax 1.69 and 120.5 ng/ml, respectively. Median maternal breast milk to plasma (M/P) ratio of TAF was 0.029; for and TFV it was 2.809. The relative infant dose of TAF was 0.005% of maternal dose, well below safety threshold of 5-10%. TFV was detectable in three out of seven infant urine samples with median steady-state concentration of 5 ng/ml being 300-2500 times less than reported adult steady-state urine concentrations in those taking TAF and TDF, respectively. CONCLUSIONS In this first pharmacokinetic study of TAF monotherapy in breastfeeding women with CHB, concentrations of TAF and TFV were low in breast milk with negligible infant exposure, supporting the use of TAF to prevent MTCT.

Maternal and infant renal safety following tenofovir disoproxil fumarate exposure during pregnancy in a randomized control trial. BMC Infect Dis 2022; 22:634.

Abstract
BACKGROUND Tenofovir disoproxil fumarate (TDF) in combination with other antiretroviral (ARV) drugs has been in clinical use for HIV treatment since its approval in 2001. Although the effectiveness of TDF in preventing perinatal HIV infection is well established, information about renal safety during pregnancy is still limited. TRIAL DESIGN The IMPAACT PROMISE study was an open-label, strategy trial that randomized pregnant women to one of three arms: TDF based antiretroviral therapy (ART), zidovudine (ZDV) based ART, and ZDV alone (standard of care at start of enrollment). The P1084s substudy was a nested, comparative study of renal outcomes in women and their infants. METHODS PROMISE participants (n = 3543) were assessed for renal dysfunction using calculated creatinine clearance (CrCl) at study entry (> 14 weeks gestation), delivery, and postpartum weeks 6, 26, and 74. Of these women, 479 were enrolled in the P1084s substudy that also assessed maternal calcium and phosphate as well as infant calculated CrCl, calcium, and phosphate at birth. RESULTS Among the 1338 women who could be randomized to TDF, less than 1% had a baseline calculated CrCl below 80 mL/min. The mean (standard deviation) maternal calculated CrCl at delivery in the TDF-ART arm [147.0 mL/min (51.4)] was lower than the ZDV-ART [155.0 mL/min (43.3); primary comparison] and the ZDV Alone [158.5 mL/min (45.0)] arms; the mean differences (95% confidence interval) were - 8.0 mL/min (- 14.5, - 1.5) and - 11.5 mL/min (- 18.0, - 4.9), respectively. The TDF-ART arm had lower mean maternal phosphate at delivery compared with the ZDV-ART [- 0.14 mg/dL (- 0.28, - 0.01)] and the ZDV Alone [- 0.17 mg/dL (- 0.31, - 0.02)] arms, and a greater percentage of maternal hypophosphatemia at delivery (4.23%) compared with the ZDV-ART (1.38%) and the ZDV Alone (1.46%) arms. Maternal calcium was similar between arms. In infants, mean calculated CrCl, calcium, and phosphate at birth were similar between arms (all CIs included 0). CONCLUSIONS Although mean maternal calculated CrCl at Delivery was lower in the TDF-ART arm, the difference between arms is unlikely to be clinically significant. During pregnancy, the TDF-ART regimen had no observed safety concerns for maternal or infant renal function. TRIAL REGISTRATION NCT01061151 on 10/02/2010 for PROMISE (1077BF). NCT01066858 on 10/02/2010 for P1084s.

Abstract
OBJECTIVE The aim of this study was to understand predictors of adverse pregnancy outcomes (APOs) among women on antiretroviral treatment (ART). DESIGN A longitudinal cohort. METHODS Participants from the Mobile WAChX trial were evaluated for APOs, including stillbirth (fetal death at ≥20 weeks' gestation), preterm birth (PTB, livebirth at <37 weeks' gestation,) and neonatal death (NND, ≤28 days after live birth). Predictors were determined by univariable and multivariable Cox proportional hazards and log-binomial models. RESULTS Among 774 women included, median age was 27 years and 29.0% had unsuppressed HIV viral load (>1000 copies/ml) at enrollment. Half (55.1%) started ART prepregnancy, 89.1% on tenofovir-based regimens. Women with depression had a higher risk of stillbirth (adjusted hazard ratio [aHR] 2.93, 95% confidence interval (95% CI) 1.04-8.23), and women with lower social support score had higher risk of late stillbirth (aHR 11.74, 2.47-55.86). Among 740 livebirths, 201 (27.2%) were preterm and 22 (3.0%) experienced NND. PTB was associated with unsuppressed maternal viral load (adjusted prevalence ratio [aPR] 1.28, 95% CI 1.02-1.61), intimate partner violence (IPV) in pregnancy (aPR 1.94, 95% CI 1.28-2.94), and history of any sexually transmitted infection (STI) (aPR 1.63, 95% CI 1.06-2.51). NND was associated with PTB (aPR 2.53, 95% CI 1.10-5.78) and STI history (aPR 4.25, 95% CI 1.39-13.06). Most associations retained significance in the subgroup of women with viral suppression. CONCLUSION Maternal viremia during pregnancy predicted PTB as did IPV, lower education, and STI history, while psychosocial stressors predicted stillbirth. Implementing mental health services, ART adherence, partner support, and routine STI screening and treatment could reduce APOs among women with HIV in sub-Saharan Africa settings.

Use of antiretroviral therapy in pregnancy and association with birth outcome among women living with HIV in Denmark: A nationwide, population-based cohort study. HIV Med 2022; 23:1007-1018.

Abstract
Objective To describe antiretroviral therapy (ART) regimens during pregnancy among women living with HIV (WLWH) in Denmark and to examine the association between ART use in pregnancy and adverse birth outcomes. Methods A population‐based cohort study including all pregnancies among WLWH in Denmark between 2000 and 2019. Data were collected through national registries. Temporal trends of ART use in pregnancy were evaluated. Logistic regression models were used to examine the association of ART use in pregnancy and other risk factors with adverse birth outcomes. Results In total, 589 pregnancies were included. Combination treatment with a nucleoside reverse transcriptase inhibitor (NRTI) and a protease inhibitor (PI) was the most common ART regimen (96%). ART regimen, PI use in pregnancy and timing of ART initiation were not significantly associated with increased odds of preterm birth, small for gestational age or low birth weight. First‐trimester initiation of ART was significantly associated with increased odds of intrauterine growth restriction in the multivariate analysis [adjusted odds ratio (aOR) = 3.78, 95% confidence interval (CI): 1.23–11.59], while first trimester PI use was associated with increased odds of IUGR in the univariate analysis only [OR = 3.24, 95% CI: 1.13–9.30]. Smoking, comorbidity, and maternal HIV RNA ≥ 50 copies/mL were independently associated with increased odds of adverse birth outcomes. Conclusions Pregnant WLWH living in Denmark are generally well treated with HIV RNA < 50 copies/mL at delivery and NRTI + PI as the most common ART regimen used in pregnancy. Initiation of ART in the first trimester may be associated with poor fetal growth. The association between ART use in pregnancy and adverse birth outcomes may partly be explained by maternal risk factors.

Abstract
OBJECTIVE To evaluate the associations of HIV infection with preterm birth (PTB), and of HIV antiretroviral therapy (ART) with PTB. METHODS We analysed singleton live-born pregnancies among women from 1995 to 2019 in the Women's Interagency HIV Study, a prospective cohort of US women with, or at risk for, HIV. The primary exposures were HIV status and ART use before delivery [none, monotherapy or dual therapy, or highly active antiretroviral therapy (HAART)]. The primary outcome was PTB < 34 weeks, and, secondarily, < 28 and < 37 weeks. We analysed self-reported birth data, and separately modelled the associations between HIV and PTB, and between ART and PTB, among women with HIV. We used modified Poisson regression, and adjusted for age, race, parity, tobacco use and delivery year, and, when modelling the impact of ART, duration from HIV diagnosis to delivery, nadir CD4 count, and pre-pregnancy viral load and CD4 count. RESULTS We analysed 488 singleton deliveries (56% exposed to HIV) to 383 women. The risk of PTB < 34 weeks was similar among women with and without HIV, but the risk of PTB < 37 weeks was higher [32% vs. 23%; adjusted risk ratio (aRR) = 1.43; 95% confidence interval (CI): 1.07-1.91] among women with HIV. The risk of PTB < 34 weeks was lower among women with HIV receiving HAART than among those receiving no ART (7% vs. 26%; aRR:0.19; 95% CI: 0.08-0.44). The associations between HAART and PTB < 28 and < 37 weeks were similar. CONCLUSIONS Antiretroviral therapy exposure was associated with a decreased risk of PTB among a US cohort of women with HIV. Given the growing concerns about ART and adverse pregnancy outcomes, this finding that ART may be protective for PTB is reassuring.

Abstract
OBJECTIVES To determine knowledge, attitude and practice (KAP) and antiviral therapy's acceptance during pregnancy of pregnant women with hepatitis B and influencing factors. DESIGN Case-comparison study. SETTING The study was conducted in Zhejiang province, China, from September 2019 to December 2020. PARTICIPANTS Pregnant and postpartum women with chronic hepatitis B. PRIMARY AND SECONDARY OUTCOME MEASURES The stress scores, self-assessed health score, KAP, antiviral therapy's acceptance rate during pregnancy and influencing factors were analysed. The Perceived Stress Scale-10 was used to assess stress. Logistic regression was used to analyse influencing factors on antiviral therapy. RESULTS The self-assessed health score of pregnant women without liver diseases (82.4±9.3) was significantly higher than that of pregnant women with chronic hepatitis B (75.5±9.5) and postpartum (75.1±14.1). Psychological stress of pregnant women with chronic hepatitis B was significantly high with a 14.9±3.6 score, but there was no significant difference between hepatitis B postpartum and non-liver disease women (12.7±3.5 vs 12.9±3.5, p=0.75). The acceptance rate of pregnant women with hepatitis B for antiviral therapy was 84.2%, while that of postpartum women was even higher. Logistic regression analysis showed that patients with positive hepatitis B e antigen (HBeAg) (OR, 3.35; 95% CI, 1.21 to 9.26) and higher scores on hepatitis B-related knowledge (OR, 3.52, 95% CI, 2.18 to 5.69) were more likely to accept antiviral therapy during pregnancy. CONCLUSIONS Pregnant women with hepatitis B in Zhejiang have heavy psychological stress and a high antiviral therapy acceptance rate during pregnancy. Acceptance is related to HBeAg status and level of understanding of hepatitis B during pregnancy. It is necessary to provide education on hepatitis B to reduce psychological stress and increase acceptance of antiviral therapy during pregnancy.

Abstract
HIV prevention is critically important during pregnancy, however, pre-exposure prophylaxis (PrEP) is underutilized. We conducted a survey of pregnant and non-pregnant women in a high HIV prevalence community in Washington D.C. to evaluate determinants of PrEP initiation during pregnancy. 201 pregnant women and a reference population of 1103 non-pregnant women completed the survey. Among pregnant women, mean age was 26.9 years; the majority were Black with household-incomes below the federal poverty level. Despite low perceived risk of HIV acquisition and low prior awareness of PrEP, 10.5% of respondents planned to initiate PrEP during pregnancy. Pregnant women identified safety, efficacy, and social network and medical provider support as key factors in PrEP uptake intention. The belief that PrEP will "protect (their) baby from HIV" was associated with PrEP uptake intention during pregnancy. Concerns regarding maternal/fetal side effects, and safety in pregnancy or while breastfeeding were not identified as deterrents to uptake intention. When compared to a nonpregnant sample, there were no significant differences in uptake intention between the two samples. These findings support the need for prenatal educational interventions to promote HIV prevention during pregnancy, as well as interventions that center on the role of providers in the provision of PrEP.

Abstract
Compounds with a phosphonate group, i.e., -P(O)(OH)2 group attached directly to the molecule via a P-C bond serve as suitable non-hydrolyzable phosphate mimics in various biomedical applications. In principle, they often inhibit enzymes utilizing various phosphates as substrates. In this review we focus mainly on biologically active phosphonates that originated from our institute (Institute of Organic Chemistry and Biochemistry in Prague); i.e., acyclic nucleoside phosphonates (ANPs, e.g., adefovir, tenofovir, and cidofovir) and derivatives of non-nucleoside phosphonates such as 2-(phosphonomethyl) pentanedioic acid (2-PMPA). Principal strategies of their syntheses and modifications to prodrugs is reported. Besides clinically used ANP antivirals, a special attention is paid to new biologically active molecules with respect to emerging infections and arising resistance of many pathogens against standard treatments. These new structures include 2,4-diamino-6-[2-(phosphonomethoxy)ethoxy]pyrimidines or so-called "open-ring" derivatives, acyclic nucleoside phosphonates with 5-azacytosine as a base moiety, side-chain fluorinated ANPs, aza/deazapurine ANPs. When transformed into an appropriate prodrug by derivatizing their charged functionalities, all these compounds show promising potential to become drug candidates for the treatment of viral infections. ANP prodrugs with suitable pharmacokinetics include amino acid phosphoramidates, pivaloyloxymethyl (POM) and isopropoxycarbonyloxymethyl (POC) esters, alkyl and alkoxyalkyl esters, salicylic esters, (methyl-2-oxo-1,3-dioxol-4-yl) methyl (ODOL) esters and peptidomimetic prodrugs. We also focus on the story of cytostatics related to 9-[2-(phosphonomethoxy)ethyl]guanine and its prodrugs which eventually led to development of the veterinary drug rabacfosadine. Various new ANP structures are also currently investigated as antiparasitics, especially antimalarial agents e.g., guanine and hypoxanthine derivatives with 2-(phosphonoethoxy)ethyl moiety, their thia-analogues and N-branched derivatives. In addition to ANPs and their analogs, we also describe prodrugs of 2-(phosphonomethyl)pentanedioic acid (2-PMPA), a potent inhibitor of the enzyme glutamate carboxypeptidase II (GCPII), also known as prostate-specific membrane antigen (PSMA). Glutamate carboxypeptidase II inhibitors, including 2-PMPA have been found efficacious in various preclinical models of neurological disorders which are caused by glutamatergic excitotoxicity. Unfortunately its highly polar character and hence low bioavailability severely limits its potential for clinical use. To overcome this problem, various prodrug strategies have been used to mask carboxylates and/or phosphonate functionalities with pivaloyloxymethyl, POC, ODOL and alkyl esters. Chemistry and biological characterization led to identification of prodrugs with 44-80 fold greater oral bioavailability (tetra-ODOL-2-PMPA).

Abstract
BACKGROUND During pregnancy and postpartum period, the sexual behaviors of women and their partners change in ways that may either increase or reduce HIV risks. Pregnant women are a priority population for reducing both horizontal and vertical HIV transmission. SETTING Nine sites in 4 South African provinces. METHODS Women aged 18-30 years were randomized to receive pericoital tenofovir 1% gel or placebo gel and required to use reliable modern contraception. We compared HIV incidence in women before, during, and after pregnancy and used multivariate Cox Proportional hazards models to compare HIV incidence by pregnancy status. RESULTS Rates of pregnancy were 7.1 per 100 woman-years (95% confidence interval [CI]: 6.3 to 8.1) and highest in those who reported oral contraceptive use (25.1 per 100 woman-years; adjusted hazard ratio 22.97 higher than other women; 95% CI: 5.0 to 105.4) or had 2 children. Birth outcomes were similar between trial arms, with 59.8% having full-term live births. No difference was detected in incident HIV during pregnancy compared with nonpregnant women (2.1 versus 4.3%; hazard ratio = 0.56, 95% CI: 0.14 to 2.26). Sexual activity was low in pregnancy and the early postpartum period, as was consistent condom use. CONCLUSIONS Pregnancy incidence was high despite trial participation being contingent on contraceptive use. We found no evidence that rates of HIV acquisition were elevated in pregnancy when compared with those in nonpregnant women. Risks from reductions in condom use may be offset by reduced sexual activity. Nevertheless, high HIV incidence in both pregnant and nonpregnant women supports consideration of introducing antiretroviral-containing pre-exposure prophylaxis for pregnant and nonpregnant women in high HIV prevalence settings.

Abstract
Introduction: Pregnancy is a period of elevated HIV risk in high-burden settings, motivating the need for prevention tools that are both safe for use and effective during pregnancy. Oral pre-exposure prophylaxis (PrEP) containing tenofovir disoproxil fumarate (TDF) is recommended by the World Health Organization, including for pregnant and postpartum women at substantial risk of HIV infection. Although TDF use during pregnancy appears generally safe, data on PrEP use during pregnancy remain limited.Areas covered: We provide an overview of the clinical pharmacology and efficacy of daily TDF-based PrEP and summarize current evidence on the safety of PrEP use by pregnant HIV-uninfected women. We synthesize relevant studies assessing pregnancy outcomes among pregnant women who are living with HIV (WLHIV) and using TDF-based therapy. Finally, we make comparison to the safety profiles of other emerging HIV prevention options.Expert opinion: The current evidence indicates that TDF/FTC PrEP use is not associated with increased risk of adverse pregnancy and early infant growth outcomes. While safety data are generally reassuring, there is need for continued accrual of data on growth and pregnancy outcomes in PrEP research, implementation projects, and controlled pharmacokinetic studies to support current evidence and to understand concentration-efficacy relationship in pregnant women.

Abstract
The effectiveness of antiretroviral therapy (ART) depends on prompt uptake of treatment and a high level of adherence over the long-term, yet these behaviors are suboptimal. Previous interventions have significantly improved adherence but effect sizes are generally small. The aim of this article is to describe the design and content of an intervention to support uptake and adherence to treatment in HIV positive patients (SUPA intervention), utilizing cognitive behavioral and motivational interviewing (MI) techniques. The intervention was developed in line with Medical Research Council (MRC) guidance for the development of complex interventions and informed by the NICE (National Institute for Health and Care Excellence) Guidelines for adherence, empirical evidence and focus groups. Behavior change techniques were mapped to perceptual and practical barriers to uptake and adherence to ART, identified in previous research. Intervention materials were designed and later discussed within focus groups, where feedback enabled an iterative process of development. We conclude it is possible to transparently report the design and content of a theory-based intervention to increase uptake and adherence to ART. The intervention has been evaluated within a randomized controlled trial (RCT) at 10 HIV clinics in England, the results of which will be reported elsewhere.

Abstract
Importance Vertical hepatitis B virus (HBV) transmission is the important route of chronic HBV infection. Although infant immunoprophylaxis is effective, a significant number of infants still become infected, most are associated with intrauterine infection. New evidences support intrauterine treatment in cases of high risk. Objective The aim of this study was to review the current evidences and recommendations for management of HBV infection in pregnancy. Evidence Acquisition Original research articles, review articles, and guidelines were reviewed. Results The management can be summarized as follows: (1) all pregnant women should be screened for hepatitis B surface antigen (HBsAg) and antibody to HBsAg. High-risk HBsAg-negative pregnant women without immunity should be vaccinated during pregnancy. (2) HBsAg-positive pregnant women should undergo further workup for liver status and indicative factors for immunoprophylaxis failure. (3) Pregnant women should be treated with HBV DNA levels greater than 200,000 IU/mL or 6 log copies/mL. (4) Antiviral drug should be started around 28 to 32 weeks. The first-line drug is tenofovir disoproxil fumarate. (5) Delivery route should be chosen based only on obstetric indications. (6) Breastfeeding is not contraindicated because it does not increase the risk of transmission in neonates with HBV vaccine and immunoglobulin administration. (7) Neonates born to HBsAg-positive mothers should receive HBV vaccine and immunoglobulin after birth as soon as possible. (8) Follow-up of the mothers and neonates is important. Beware of hepatitis flare after birth and after antiretroviral drug discontinuation; alanine transaminase assessment every 1 to 3 months until 6 months is suggested. Also, the schedule of infant vaccination and follow-up of serologic testing at 9 to 12 months old is needed.

Abstract
The rate of mother-to-child transmission (MTCT) of HIV from breastfeeding is increasing relative to other causes of MTCT. Early effective preconception and antenatal antiretroviral therapy (ART) reduces intrauterine and intrapartum MTCT, whereas maternal post-partum HIV acquisition, untreated maternal HIV, and suboptimal postnatal maternal ART adherence increase the risk of MTCT through breastfeeding. Although the absolute number of cases of MTCT acquired through breastfeeding is decreasing, the rate of decrease is less than the decrease in intrauterine and intrapartum MTCT. Unless current strategies are universally applied, they might not be sufficient to eliminate MTCT due to breastfeeding. Urgent action is needed to evaluate and implement additional preventive biomedical strategies in high HIV prevalence and incidence settings to eliminate MTCT from breastfeeding. Preventive strategies include: pre-exposure prophylaxis in breastfeeding women who have an increased risk of acquiring HIV; postnatal reinforcement strategies, such as maternal retesting for HIV, maternal care reinforcement, and prophylaxis in infants exposed to HIV via breastmilk; and active (vaccine) or passive immunoprophylaxis with long-acting broadly neutralising antibodies.

Abstract
BACKGROUND Disparities in HIV incidence and PrEP use among Black ciswomen remain. We examine factors associated with PrEP persistence using mixed methods. SETTING Black ciswomen in Chicago, IL, prescribed PrEP at a federally qualified health center (FQHC). METHODS We used electronic health data to determine PrEP persistence (Proportion of Days Covered ≥86% at 6 months) and tested demographic and clinical factors in logistic regressions. We interviewed eight Black ciswomen, purposefully selected by PrEP persistence. RESULTS Among 112 Black ciswomen, 18% were persistent. In adjusted models, neighborhood, visit reason (at initiation), and initiation year were significantly associated with persistence. Qualitatively, we found little evidence of cost or adherence as barriers; participants reported low community awareness, importance of providers, and concerns around stigma, side effects, and pregnancy while using PrEP. CONCLUSION While persistence among Black ciswomen was low, patients were often making decisions based on perceived HIV risk. We identified real-world barriers to address in future interventions.

Abstract
OBJECTIVE To evaluate the pharmacokinetics of tenofovir alafenamide (TAF) 10 mg with cobicistat and 25 mg without boosting in pregnant and postpartum women with HIV and to characterize TAF placental transfer and infant washout pharmacokinetics. DESIGN Open-label, multicenter phase IV prospective study of TAF pharmacokinetics during pregnancy, postpartum, delivery, and infant washout. METHODS Pregnant women receiving TAF 10 mg with cobicistat or TAF 25 mg without boosting as part of clinical care had intensive pharmacokinetic assessments performed during the second and third trimesters, and 6-12 weeks postpartum. Maternal and cord blood samples were collected at delivery, and washout pharmacokinetic samples were collected in infants. TAF concentrations were quantified using liquid chromatography/mass spectrometry. Comparisons between pregnancy and postpartum were made using geometric mean ratios (90% confidence intervals) and Wilcoxon signed-rank tests. RESULTS Thirty-one pregnant women receiving TAF 10 mg with cobicistat-boosting and 27 women receiving TAF 25 mg without boosting were enrolled. TAF exposures did not significantly differ between pregnancy and postpartum when administered as 10 mg with cobicistat. Antepartum TAF exposures with the 25 mg dose were 33-43% lower in comparison with postpartum, but comparable with those measured in nonpregnant adults. TAF was below the lower limit of quantitation in 43 of 44 cord blood, 41 of 45 maternal blood at delivery, and all infant washout samples. CONCLUSION TAF exposures were comparable or higher than those measured in nonpregnant adults during pregnancy and postpartum. These findings provide reassurance on adequate TAF exposures during pregnancy, and support efforts to expand the use of TAF in pregnant women with HIV.

Abstract
: In recent years, widespread use of antiretroviral therapy (ART) during pregnancy has been increasingly effective in reducing risk of vertical transmission of HIV, with over 80% of pregnant women living with HIV now accessing ART, and a 41% reduction in new infections in children between 2010 and 2018. Despite these strides, the developmental toxicity of widely administered antiretroviral drugs (ARVs) remains poorly described and existing literature often fails to account for fetal and infant sex as a variable. Recent reports have identified associations between in-utero exposure to commonly used antiretroviral regimens and alteration in neurodevelopment, growth, and metabolism amongst children who are HIV-exposed but uninfected, with findings of sex differences in the prevalence and severity of ARV toxicity. These differences are potentially explained by variable exposure to ARV drugs in utero or exacerbation of existing sex-linked risk factors. Fetal ARV exposure is mediated by placental and fetal drug transporters and metabolic enzymes, which may contribute to the manifestation of sex differences. Existing evidence of sex differences in ARV toxicity in fetal development is concerning, and demands further research to guide optimal treatment options for maternal health and prevention of vertical HIV transmission.

[PMID: 32424746 DOI: 10.1007/s00431-020-03660-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/24/2020] [Accepted: 04/22/2020] [Indexed: 12/11/2022]
Abstract
Tenofovir disoxoproxil fumarate (TDF) is recommended for antiretroviral treatment for pregnant women living with HIV. As a comparative method to study bone density, we investigated the influence of in utero tenofovir exposure on the prevalence and distribution of developmental defects of enamel (DDE) in the primary dentition, as the mineralization process in teeth is higher and more complex and thus more vulnerable. HIV-exposed children with in utero exposition to tenofovir were included in this prospective observational single-center study. Dental status and enamel defects were assessed by an experienced dentist following a standardized protocol. Further information was collected using a standardized questionnaire, available in German and English. The prevalence of developmental defects in children with intrauterine tenofovir exposure was compared with literature data from a recent study of 377 healthy children in Germany and literature data from a study of 1221 healthy African children. Thirty-one children (mean age 2.1 ± 0.3 years; 41.9% female) were included. Median tenofovir exposure in utero was 28 weeks (mean ± 10.52 SD). Prevalence of developmental defects in the primary dentition in tenofovir-exposed children was similar compared to data of unexposed children (16.1% vs. 5.3%, p = 0.051 (compared to German cohort); 16.1% vs. 33.3%, p = 0.068 (compared to African cohort)).Conclusion: HIV-uninfected infants with in utero exposure to TDF showed no significant differences in the prevalence of DDE in comparison to cross-sectional data of HIV- and TDF-unexposed children; thus, the in utero exposure to TDF did not negatively influence the prevalence or distribution of DDE. What is Known: • There are no data available on the prevalence of developmental defects of enamel (DDE) in the primary dentition in intrauterine HIV- and tenofovir-exposed children. • Conclusions can be drawn from intrauterine milk tooth development to bone development and mineralization. What is New: • Prevalence of developmental defects in the primary dentition in tenofovir-exposed children was similar compared to data of unexposed children. • Preterm birth and hospitalization did not show a significant association on the prevalence of developmental defects in the primary dentition.

Abstract
Perinatal transmission of hepatitis B virus continues to be a serious global public health concern. Transmission failures are related to high maternal viremia. Several antiviral therapies reduce maternal viremia around the time of delivery and decrease maternal-to-child-transmission. This chapter is a review of current studies that, ultimately, have provided strong evidence for the efficacy and safety of 3 antiviral drugs in pregnancy-lamivudine, telbivudine and tenofovir. The latter drug is the particular focus of this chapter which will show that tenofovir is the preferred antiviral therapy in pregnant women because of its potency, safety profile, and low risk of resistance.

Abstract
The Senegal pre-exposure prophylaxis (PrEP) Demonstration Project was an open-label cohort study assessing the delivery of daily oral PrEP to HIV-negative female sex workers (FSWs) in four Ministry of Health (MoH)-run clinics in Dakar, Senegal. We assessed uptake, retention in care, and adherence over up to 12 months of follow-up as well as HIV infection rates. Between July and November 2015, 350 individuals were approached and 324 (92.6%) were preliminarily eligible. Uptake was high, with 82.4% of eligible participants choosing to enroll and take PrEP. The mean age of those enrolled was 37.7 years (SD = 8.7), and approximately half had not attended school (41.2%). Among the 267 participants who were prescribed PrEP, 79.9 and 73.4% were retained in PrEP care at 6 and 12 months, respectively. Older age among FSWs was found to be the only significant predictor of lower discontinuation. We did not find significant differences in retention by site, education, condom use, or HIV risk perception. There were no new HIV infections at follow-up. Our results showed evidence of high interest in PrEP and very good PrEP retention rates among FSWs at 12-month follow-up when offered in MoH-run clinics, with older age as the only significant predictor of higher PrEP retention. This highlights the role that these clinics can play in expanding PrEP access nationwide.

Abstract
BACKGROUND There are concerns about the adverse effect of in-utero exposure to antiretroviral therapy (ART) on the growth of HIV exposed-uninfected (HEU) infants. We compared growth of HEU-infants according to the timing and type of ART exposure. METHODS A retrospective cohort study was conducted by abstracting clinical data from HIV-infected mothers and HEU-infants in Addis Ababa, Ethiopia between February 2013 and October 2016. Mixed-effects linear models were used to compare changes in weight and length and cox proportional hazard models were used to evaluate stunting (length-for-age z score <-2.0) and underweight (weight-for-age z score <-2.0). RESULTS A total of 624 HEU-infants were included in the analyses. Infants exposed to ART from conception had a lower rate of change in length [β = -0.54, 95% confidence interval (CI): -1.00 to -0.08] the first 3 months of life, as compared with infants exposed from late pregnancy. Risk of stunting was 51.9 per 100 person-years and risk of underweight was 26.7 per 100 person-years. Exposure to ART from conception was associated with a higher rate of stunting as compared with exposure from late pregnancy (adjusted hazard ratio = 1.95, 95% CI: 1.27-2.99). Infants born to mothers with advanced disease had a higher incidence of underweight compared with infants born to mothers with early-stage disease adjusted hazard ratio = 1.99, 95% CI: 1.32-3.03). CONCLUSIONS In HEU-infants, exposure to ART from conception was associated with decrease growth during early infancy and higher incidence of stunting compared with treatment exposure later in pregnancy. Close monitoring of HEU-infants' growth and prompt nutritional intervention is essential.

Abstract
Breastfeeding is a crucial child survival intervention. However, the potential for transmission of viral infections from mother to child presents the dilemma of how best to interpret the benefits and risks of breastfeeding in different settings. In this Review, we compare the transmission dynamics, risk factors, and outcomes of infection with three chronic viruses transmitted through breastmilk: cytomegalovirus, human T-cell lymphotropic virus type 1, and HIV. We provide an overview of intervention approaches and discuss scientific, policy, and programming gaps in the understanding of these major global infections.

Abstract
PURPOSE OF REVIEW In the era of modern bone-friendly antiretroviral therapy (ART) regimens for people living with HIV (PLWH), this review discusses the research gaps and management concerns that remain for individuals who have already been exposed to ART with negative effects on bone metabolism, especially children and adolescents who have not acquired peak bone mass, and older adults who have additional risk factors for fracture. RECENT FINDINGS Data now support the use of avoidance of TDF and use of bone-friendly regimens that include integrase strand transfer inhibitors in PLWH with increased risk of fracture for either ART initiation or switch. Despite significant advances in our understanding of ART choice for PLWH with regard to bone health, additional diagnostic tests to determine fracture risk and management strategies beyond ART choice are necessary, especially in vulnerable PLWH populations, such as children and adolescents and older adults.

Abstract
BACKGROUND & AIMS Tenofovir disoproxil fumarate (TDF) is the preferred treatment to prevent maternal transmission of HBV, owing to its efficacy and safety. However, data are lacking on the long-term safety outcomes in children following fetal exposure to TDF. METHODS Children participating in a prospective, multisite trial of maternal TDF treatment during late pregnancy were recruited for follow-up visits once a year. Growth parameters, serum biochemistry, HBV serology, and bone mineral density (BMD) by dual-energy x-ray absorptiometery scan were measured. RESULTS One hundred and twenty-eight children, 71 in the TDF and 57 in the control group, completed 255 follow-up visits at the age of 2 to 7 (median, 4.08) years. No differences in z-scores for weight-for-age (0.26 ± 0.90 vs. 0.22 ± 0.99, p = 0.481), z-scores for height-for-age (0.20 ± 1.02 vs. 0.25 ± 0.98, p = 0.812), and estimated glomerular filtration rate (169.12 ± 50.48 vs. 169.06 ± 34.46 ml/min/1.73m2, p = 0.479) were detected. After adjustment for age, sex and HBV status by multiple linear regression, children in the TDF and control group had comparable levels of serum calcium, phosphorus, bone-specific alkaline phosphatase, calcidiol and BMD of lumbar spines (0.55 ± 0.01 vs. 0.57 ± 0.01 g/cm2, p = 0.159) and left hip (0.56 ± 0.01 vs. 0.56 ± 0.01 g/cm2, p = 0.926). CONCLUSIONS Children of HBV-infected mothers who did or did not receive tenofovir disoproxil fumarate treatment during late pregnancy had comparable long-term growth, renal function, and bone development up to 6-7 years after delivery. CLINICAL TRIAL NUMBER NCT01312012 (ClinicalTrials.gov) LAY SUMMARY: Currently there are insufficient long-term safety data in children born to mothers who took antiviral agents during pregnancy to prevent mother-to-infant transmission of hepatitis B virus (HBV). In this study, we found that children of HBV-infected mothers who did or did not receive tenofovir disoproxil fumarate treatment during late pregnancy had comparable long-term growth, renal function, and bone development up to 6-7 years after delivery.

Abstract
Objective: The objective of the study was to compare the maternal and fetal outcomes of currently preferred tenofovir-based regimen with previous zidovudine-based regimen and also to determine whether the time of starting antiretroviral therapy (ART), whether it can affect the pregnancy and fetal outcome. Materials and Methods: Pregnant patients prescribed any of the above regimens were followed up every month till delivery and newborns for initial 6 months. Maternal endpoints were body weight, hemoglobin, and CD4 count, whereas fetal endpoints were birth weight, Apgar score, body weight, and HIV status at 6 months. Data were analyzed using ANOVA and unpaired t-test. P <0.05 was considered statistically significant. Results: A significant increase in CD4 count was observed in patients treated with both the regimens at 12 months as compared to baseline (P < 0.001 and 0.05). Moreover, a significant increase in CD4 count was observed at 12 months as compared to baseline, whether treatment was started before or after the diagnosis of pregnancy (P < 0.05 and 0.001). A significant difference in mean body weight at the end of 9 months was observed in patients wherein ART was started before or after the diagnosis of pregnancy (P < 0.005). Majority of patients had a favorable maternal outcome, while fetal birth weight, Apgar score, body weight, and HIV status were comparable at 6 months irrespective of treatment and time of starting ART. Conclusion: All ART regimens are equally effective in terms of increase in CD4 count, gestational gain in body weight, and pregnancy and fetal outcome. Furthermore, there is no significant difference in efficacy, pregnancy, and fetal outcome in women who were already on ART when diagnosed pregnancy or who were started ART later in antenatal period.

Abstract
PURPOSE OF REVIEW Although antiretroviral therapy (ART) has dramatically reduced mother to child transmission of HIV, data continue to mount that infants exposed to HIV in utero but are not infected (HEU) have serious negative health consequences compared to unexposed infants. This review evaluates recent literature on contemporary issues related to complications seen in pregnant women with HIV and their offspring. RECENT FINDINGS Current studies show that HEU infants are at a high risk of adverse outcomes, including premature birth, poor growth, neurodevelopmental impairment, immune dysfunction, infectious morbidity, and death. Etiologies for the observed clinical events and subclinical alterations are complex and multifactorial, and the long-term consequences of many findings are yet unknown. HEU infants have an unacceptable rate of morbidity and mortality from perinatal HIV and ART exposure, even in the modern ART era. Continual monitoring and reporting is imperative to protect this vulnerable population in our everchanging landscape of HIV treatment and prevention.

Abstract
Introduction: Tenofovir alafenamide (TAF)-containing fixed-dose drug combinations (FDCs) are increasingly being used in managing pregnant women living with HIV. However, TAF is not currently recommended during pregnancy due to limited pharmacokinetic and safety data. TAF, a newer nucleotide phosphonamidate prodrug of tenofovir (TFV), achieves high levels of tenofovir-diphosphate in lymphoid cells and hepatocytes, and 90% lower systemic concentrations of TFV compared to tenofovir disoproxil fumarate (TDF), thereby maximizing TAF's antiviral efficacy, potency and clinical safety.Areas covered: This review discusses the currently available information on the pharmacology of TAF in pregnant women living with HIV. Pharmacokinetic studies with TAF during pregnancy have yielded varying results compared to postpartum, but TAF exposures during pregnancy have been within the range of those typically observed in non-pregnant adults. The efficacy and safety of TAF in treatment-naïve pregnant women living with HIV is currently being evaluated in the VESTED study, a phase-III NIH randomized clinical trial.Expert opinion: Initial pregnancy data suggest that TAF-based FDCs have high efficacy and low risk of adverse effects during pregnancy. TAF is likely to become part of first-line regimens for use in pregnant women living with HIV once additional pregnancy data from phase III trials are available.

Abstract
Mother-to-child transmission of hepatitis B virus can occur during the intrauterine, antenatal and postnatal periods, with an increased risk of perinatal transmission. Appropriate management of patients who are hepatitis B surface antigen positive during pregnancy can substantially reduce the rates of perinatal transmission. Herein, two pregnant women with chronic hepatitis B are presented; one became pregnant while receiving tenofovir disoproxil fumarate and continued the treatment during pregnancy, the other discontinued tenofovir disoproxil fumarate treatment on her own due to conception, but restarted at 26 weeks of pregnancy. At birth the newborns of both women were vaccinated and immunoglobulin was given, with no perinatal transmission. Whether pregnant women should receive antiviral therapy or immunoprophylaxis still remains controversial. In order to keep the mother's liver stable and to prevent perinatal transmission, it is of paramount importance to manage pregnant women in line with the current information and guidelines.

Abstract
Intrauterine exposure to zidovudine-based combination antiretroviral therapy (cART) can cause severe anemia within the first weeks of life. Tenofovir disoproxil fumarate (TDF)-based regimens may have less hematologic side effects but may affect growth parameters. This study aimed to assess the safety of TDF for prevention of mother-to-child transmission (PMTCT) in HIV-exposed uninfected infants regarding early growth outcomes and hematologic side effects. Our retrospective observational cohort study included children born (n = 232) to HIV-infected mothers (n = 228) on cART. Blood counts were compared at birth, 4-6 weeks, and 3, 12 and 18 months of age. Growth parameters were measured at birth and 12 and 18 months of age. Data were analyzed according to treatment group (TDF and non-TDF cART regimes). The median hemoglobin (Hgb) was significantly lower in the non-TDF-based group at birth (15.4 g/dl vs. 16.9 g/dl; **p = 0.002) and at 4-6 weeks of age (9.9 g/dl vs. 10.4 g/dl; **p = 0.004). The mean corpuscular volume was higher in the non-TDF-based group (109 fl vs. 105 fl; ***p < 0.001) as well at 4-6 weeks (102 fl vs. 95 fl; ***p < 0.001). In the TDF-based group, a higher proportion of neutropenia (grade 2 and higher) compared to the non-TDF-group (21.4% vs. 11%; *p = 0.015) was observed at three months of age. This effect was transient. There was no difference in growth.Conclusions: TDF appears to have no major side effects in our cohort. Transient anemia was observed more commonly with non-TDF regimens. However, our research suggests a potential delayed effect of TDF on neutrophils at 3 months of age.What is Known:• TDF is suspected to affect the growth of HIV-exposed uninfected infants.• Non-TDF-based cART regimes for prevention of mother-to-child transmission of HIV often result in transient anemia in the infant.What is New:• TDF appears to have no major side effects regarding the growth of HIV-exposed uninfected infants.• Our research suggests a potential delayed effect of TDF on neutrophils at 3 months of age in these infants.

Abstract
INTRODUCTION HIV incidence is high during pregnancy and breastfeeding with HIV acquisition risk more than doubling during pregnancy and the postpartum period compared to when women are not pregnant. The World Health Organization recommends offering pre-exposure prophylaxis (PrEP) to pregnant and postpartum women at substantial risk of HIV infection. However, maternal PrEP national guidelines differ and most countries with high maternal HIV incidence are not offering PrEP. We conducted a systematic review of recent research on PrEP safety in pregnancy to inform national policy and rollout. METHODS We used a standard Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach to conduct a systematic review by searching for completed, ongoing, or planned PrEP in pregnancy projects or studies from clinicaltrials.gov, PubMed and NIH RePORTER from 2014 to March 2019. We performed a systematic review of studies that assess tenofovir disoproxil fumarate (TDF)-based oral PrEP safety in pregnant and breastfeeding HIV-uninfected women. RESULTS AND DISCUSSION We identified 14 completed (n = 5) and ongoing/planned (n = 9) studies that evaluate maternal and/or infant outcomes following PrEP exposure during pregnancy or breastfeeding. None of the completed studies found differences in pregnancy or perinatal outcomes associated with PrEP exposure. Nine ongoing studies, to be completed by 2022, will provide data on >6200 additional PrEP-exposed pregnancies and assess perinatal, infant growth and bone health outcomes, expanding by sixfold the data on PrEP safety in pregnancy. Research gaps include limited data on (1) accurately measured PrEP exposure within maternal and infant populations including drug levels needed for maternal protection; (2) uncommon perinatal outcomes (e.g. congenital anomalies); (3) infant outcomes such as bone growth beyond one year following PrEP exposure; (4) outcomes in HIV-uninfected women who use PrEP during pregnancy and/or lactation. CONCLUSIONS Expanding delivery of PrEP is an essential strategy to reduce HIV incidence in pregnancy and breastfeeding women. Early safety studies of PrEP among pregnant women without HIV infection are reassuring and ongoing/planned studies will contribute extensive new data to bolster the safety profile of PrEP use in pregnancy. However, addressing research gaps is essential to expanding PrEP delivery for women in the context of pregnancy.

Abstract
Background Lifelong antiretroviral therapy (ART) reduces mother-to-child HIV transmission (MTCT) and improves maternal health. Data on the outcomes of HIV-exposed infants (HEI) compared to their unexposed counterparts in the era of universal ART is limited. We compared birth and 6-week outcomes among infants born to HIV-positive and HIV-negative women in Lesotho. Methods 941 HIV-negative and 653 HIV-positive pregnant women were enrolled in an observational cohort to evaluate the effectiveness of prevention of mother-to-child HIV transmission (PMTCT) program after implementation of universal maternal ART in 14 health facilities. Pregnancy, delivery, birth, and 6-week data were collected through participant interviews and medical record review. DNA PCR testing for HEI was conducted within 2 weeks of birth and at around 6 weeks of age. Data were analysed to estimate the distribution of birth outcomes, mortality, HIV transmission and HIV-free survival at 6 weeks. Results HIV-positive women were older (mean age of 28.7 vs. 24.4 years) and presented for antenatal care earlier (mean gestational age of 23.0 weeks vs 25.3 weeks) than HIV-negative women. Prematurity was more frequent among HEI, 7.8% vs. 3.6%. There was no difference in rates of congenital anomalies between HEI (1.0%) and HIV-unexposed infants (HUI) (0.6%). Cumulative HIV transmission was 0.9% (N = 4/431) (95% CI:0.25–2.36) at birth and 1.0% (N = 6/583) (95% CI:0.38–2.23) at 6 weeks. Overall mortality, including stillbirths, was 5.2% and 6.0% by 6 weeks for HUI and HEI respectively. Among liveborn infants, 6-week HIV-free survival for HEI was 95.6% (95% CI:93.7–97.1) compared to 96.8% (95% CI:95.4–97.9) survival for HUI. Conclusions Implementation of universal maternal ART lowers MTCT at 6 weeks of age with no differences in congenital anomalies or early mortality between HIV exposed Infants and HIV unexposed infants. However, HIV exposed infants continue to have high rates of prematurity despite improved maternal health on ART.

Abstract
OBJECTIVE To evaluate the association between HIV antiretroviral therapy (ART) and preterm birth (PTB), when defined by gold standard antenatal ultrasound versus newborn exam. DESIGN A secondary analysis of the PROMISE 1077BF/1077FF randomized controlled trial, which compared antiretroviral strategies to reduce perinatal HIV transmission and improve maternal health. The trial used newborn exam (i.e. New Ballard Score, NBS) to assess gestational age. This analysis included liveborn singleton pregnancies with both newborn exam and ultrasound data. The primary exposure was the trial's antiretroviral strategies: zidovudine with intrapartum nevirapine ('ZDV alone'); zidovudine/lamivudine/lopinavir-ritonavir ('ZDV-based ART'); or tenofovir/emtricitabine/lopinavir-ritonavir ('TDF-based ART'). The primary outcome was PTB less than 37 and less than 34 weeks based on the gold standard of ultrasound dating. We evaluated the association between antiretroviral strategy and PTB. We fit multivariable logistic regression models, adjusting for maternal characteristics, obstetric history, and HIV disease severity. RESULTS Among 720 assessed pregnant women, PTB less than 37 weeks was 15.4% by NBS and 18.3% by ultrasound. The NBS was specific but not sensitive for PTB less than 37 weeks (92.0% and 48.5%). Women receiving ZDV-based and TDF-based ART had significantly higher odds of PTB less than 37 by ultrasound compared with ZDV alone (adjusted odds ratios: 1.68; 95% confidence interval 1.10-2.57, and 2.71; 95% confidence interval 1.39-5.29), as well as for PTB less than 34 weeks. These results held for ultrasounds performed less than 24 weeks, and were generally consistent with prior analyses from the PROMISE trial using the NBS. CONCLUSION Women starting HIV ART in pregnancy remained at higher risk of PTB when determined by ultrasound, consistent with prior data using newborn exam. However, newborn exam misclassified cases of PTB compared with gold standard ultrasound.

Abstract
BACKGROUND Relatively little is known about the frequency and factors associated with miscarriage among women living with HIV. OBJECTIVE The objective of the study was to evaluate factors associated with miscarriage among women enrolled in the Women's Interagency HIV Study. STUDY DESIGN We conducted an analysis of longitudinal data collected from Oct. 1, 1994, to Sept. 30, 2017. Women who attended at least 2 Women's Interagency HIV Study visits and reported pregnancy during follow-up were included. Miscarriage was defined as spontaneous loss of pregnancy before 20 weeks of gestation based on self-report assessed at biannual visits. We modeled the association between demographic, behavioral, and clinical covariates and miscarriage (vs live birth) for women overall and stratified by HIV status using mixed-model logistic regression. RESULTS Similar proportions of women living with and without HIV experienced miscarriage (37% and 39%, respectively, P = .638). In adjusted analyses, smoking tobacco (adjusted odds ratio, 2.0), alcohol use (adjusted odds ratio, 4.0), and marijuana use (adjusted odds ratio, 2.0) were associated with miscarriage. Among women living with HIV, low HIV viral load (<4 log10 copies/mL) (adjusted odds ratio, 0.5) and protease inhibitor (adjusted odds ratio, 0.4) vs the nonuse of combination antiretroviral therapy use were protective against miscarriage. CONCLUSION We did not find an increased odds of miscarriage among women living with HIV compared with uninfected women; however, poorly controlled HIV infection was associated with increased miscarriage risk. Higher miscarriage risk among women exposed to tobacco, alcohol, and marijuana highlight potentially modifiable behaviors. Given previous concern about antiretroviral therapy and adverse pregnancy outcomes, the novel protective association between protease inhibitors compared with non-combination antiretroviral therapy and miscarriage in this study is reassuring.

Comparing the Efficacy and Safety of Treating Chronic Hepatitis B Infection during Pregnancy with Lamivudine, Telbivudine, and Tenofovir: A Meta-analysis. J Clin Transl Hepatol 2019; 7:197-212. [PMID: 31608211 PMCID: PMC6783676 DOI: 10.14218/jcth.2019.00021] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Revised: 08/13/2019] [Accepted: 08/19/2019] [Indexed: 12/14/2022] Open
Abstract
Background and Aims: The perinatal transmission of hepatitis B virus (HBV) remains an important global health problem. Here, a systematic review and meta-analysis were conducted to evaluate the evidence regarding the efficacy and maternal/fetal safety of treating pregnant women with lamivudine, telbivudine (LdT), and tenofovir (TDF). Methods: A PubMed and Scopus search resulted in 1,076 records, which were reduced to 36, containing 7,717 pregnant women with chronic HBV infection and 7467 infants meeting the inclusion criteria. The latest search was in August 2019. Results: Treatment with LdT, but not lamivudine and TDF, could significantly reduce the hepatitis B virus surface antigen-positive rate (odds ratio (OR) = 0.37) in infants; it also led to higher rates of hepatitis B e antigen loss (OR = 12.14), hepatitis B e antigen seroconversion (OR = 8.93), and alanine aminotransferase normalization in mothers (OR = 1.49). Each of these treatments was able to significantly reduce HBV DNA positivity at birth (total OR = 0.19) and mother-to-child-transmission of HBV (total OR = 0.15), and to cause higher rates of HBV DNA suppression in mothers (total OR = 25.53). However, nucleos(t)ide analogues might also be involved in creatine kinase elevation (total OR = 7.48). In contrast, no significant association was found between nucleos(t)ide analogue therapy and preterm/premature births, congenital malformation, low birth weight, and abortion or fetal/infant death. The results suggested LdT's high capability of preventing mother-to-child-transmission. However, TDF failed to show significant associations to a reduced risk of mother-to-child-transmission, probably due to the low number of patients included. Conclusions: Although using either lamivudine, LdT, or TDF could lead to more favorable maternal/fetal outcomes, LdT seemed to show more potential in resolving certain infant- and maternal-related outcomes. More studies on the safety profile of such treatments are required.

Abstract
Pre-exposure prophylaxis (PrEP) is a promising intervention to prevent HIV acquisition, with benefits both to the individual and to population-level health. PrEP is an opportunity to complement ongoing public health efforts to eliminate HIV. For women, PrEP can also serve as a gateway to access sexual and reproductive health (SRH) services. Clinical efficacy of PrEP was initially reported in women using a 1% tenofovir vaginal gel in 2010, followed by an efficacy trial of oral PrEP using TDF/FTC in men who have sex with men (MSM). Since then, further trials have reported efficacy in oral PrEP containing tenofovir in women and heterosexual men, while the subsequent trials for women using tenofovir gel reported no efficacy, stemming from difficulties in achieving adequate adherence. In an effort to offer women additional choices to oral PrEP, alternative modalities are being tested in clinical research, including long-acting injectable formulations and intra-vaginal rings. In 2015, a meta-analysis of clinic trials and open-label extension studies led to the World Health Organization (WHO) strongly recommending the provision of oral PrEP containing tenofovir for any person at substantial risk of HIV infection, irrespective of gender or population group. Currently, PrEP services for women around the world, including those who are either pregnant or breastfeeding, remain limited. Outside sub-Saharan Africa, most PrEP programmes are focused on MSM. South Africa, Kenya, and the USA have the greatest utilization of oral PrEP by women. Yet, since 2012, of the estimated > 300,000 people globally who have initiated PrEP, a minority are women. In this narrative review, we examine the most recent literature on clinical and implementation PrEP research among women. We highlight the high burden of disease related to common sexually transmitted infections (STIs) in women, and the opportunity to integrate PrEP and other HIV prevention services, STI case management, and family planning services, as part of a more robust package of SRH services. Raising awareness on PrEP amongst women and their healthcare providers, minimizing gaps in access, and ensuring adherence and persistence of PrEP during periods of risk are critical issues if PrEP can have a meaningful impact on reducing HIV incidence in women globally.

Perinatal outcomes following maternal pre-exposure prophylaxis (PrEP) use during pregnancy: results from a large PrEP implementation program in Kenya. J Int AIDS Soc 2019; 22:e25378. [PMID: 31498563 PMCID: PMC6733245 DOI: 10.1002/jia2.25378] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Accepted: 07/31/2019] [Indexed: 12/27/2022] Open
Abstract
INTRODUCTION The World Health Organization, while recommending pre-exposure prophylaxis (PrEP) for HIV-negative pregnant and postpartum women in HIV high-burden settings, advocates for continued safety evaluation of PrEP in this population. METHODS The PrEP Implementation in Young Women and Adolescents (PrIYA) program delivered PrEP to pregnant and postpartum women integrated within routine maternal and child health clinics (MCH) at 16 sites in Western Kenya. PrEP exposure and perinatal outcome data were collected among women obtaining postnatal services during programme evaluation. PrEP use was self-reported and confirmed with clinical records. Perinatal outcomes including gestational age at birth, birthweight, congenital malformations and infant growth outcomes were abstracted from clinical records for mother-infant pairs attending the six week visit. Associations between infant outcomes and maternal prenatal PrEP use were assessed using univariate and multivariate logistic and linear regression. RESULTS The PrIYA evaluation identified 1530 postpartum mother-infant pairs with data on prenatal PrEP exposure: 206 with prenatal PrEP use, 1324 without. Median maternal age was 24 years in both groups. PrEP users (any reported PrEP use) were significantly more likely to report HIV risk factors such as: intimate partner violence, sexually transmitted infections and having a partner with positive or unknown HIV status. Most mothers initiated PrEP during the second trimester (n = 116, 57%) and used PrEP for more than one month (n = 110, 58%). The mean birthweight was 3.3 kg and gestational age at birth was 38.5 weeks in both groups. There were no major differences between PrEP exposed and unexposed infants in rates of preterm birth and low birthweight. There were no congenital malformations identified in the PrEP-exposed group and five reported in the PrEP unexposed group. At six weeks postpartum, infants in both groups had similar growth. No differences in infant outcomes were found by duration PrEP exposure, trimester of PrEP initiation, a subset analysis of women 15 to 24 years old or in multivariate analyses. This analysis demonstrates that monitoring of infant outcomes is feasible within large-scale programmatic implementation of PrEP among pregnant and postpartum populations. CONCLUSIONS Pregnancy outcomes and early infant growth did not differ by PrEP exposure.

Abstract
OBJECTIVES Malawi's Option B+ universal antiretroviral therapy (ART) program for pregnant and breastfeeding women does not include routine laboratory monitoring. We report safety outcomes of pregnant women who initiated ART through Option B+. METHODS We analysed 12-month data from an observational cohort study on Option B+ among women newly initiating tenofovir/lamivudine/efavirenz (TDF/3TC/EFV) at a government antenatal clinic in Lilongwe, Malawi. Proportions of women engaged in care, incidence of DAIDS grade ≥ 2 laboratory toxicity, grade ≥ 3 adverse events (AEs), viral suppression (<1000 copies/mL), birth outcomes and infant HIV infections are reported. RESULTS At ART initiation, participants (n = 299) had a median age of 26 years (IQR 22-30), median CD4 count of 352 cells/μl (IQR 231-520) and 94% were in WHO Stage 1. We noted 76 incident DAIDS Grade ≥ 2 laboratory results among 58 women, most commonly elevated liver function tests (n = 30 events) and low haemoglobin (n = 27). No women had elevated creatinine. Clinical AEs (n = 45) were predominantly infectious diseases and Grade 3. Five participants (2%) discontinued TDF/3TC/EFV due to virologic failure (3) or toxicity (2). Twelve months after ART initiation, most women were engaged in care (89%) and had HIV RNA < 1000 copies/ml (90%). 8% of pregnancies resulted in preterm birth, 9% were low birthweight (<2500 g), and 2% resulted in infant HIV infection at 6 weeks post-delivery. CONCLUSION Most women remained on ART and were virally suppressed 12 months after starting Option B+. Few infants contracted HIV perinatally. While some women experienced adverse laboratory events, clinical symptom monitoring is likely reasonable.
